Different "breeds" of Xenomorph. . .

Sure thing @LyleP - Shaw IMO gets dragged off by the storm and may be the first human to actually come face to face with the Engineers. I would imagine that this is either non-hostile or she has no memory of what they do to her - anal probe I expect lols.

All of above are very valid points. Love reading them. However the first Xeno we saw in Alien would infact be a first generation human Xenomorh hybrid bred from the offspring of a SJ Xenomorph hybrid bred from what I think would have been the originator Xeno, which I think we are all about to know all about in the prequel Prometheus. This would mean that all the Xenos we have seen so far have had some form of human DNA in them which they have inherited in one way or another. I am hoping that Ridley is going to show us this Originator stage, perhaps its simply the green goo we see in the teaser or perhaps a full blown creature. If its a creature I expect that the shape will be entirely different, but it exoskeleton will look related to the Alien Xeno. Well lets say that what Im jhoping to see.

@Brego - Yeah I definitly think we'll see the originality of the Xenomorph creature! I can't wait! But seeing what the creature looks like before it's interaction with the human species would be interesting. . . Everyone read that "Pinocchio" thread, best theory around thus far!

Agreed Xenophobe. Im thinking along the lines of a couple of Gigers landscapes in his various books. Basically a cross between formed and unformed structure and fluidity, very Alien to our eyes, horrid and beautiful at the same time. As Ridley once said "you dont know if its going to Fuck you or Kill you!" Getting even more excited.
